I don’t know why it happens, it literally makes no sense. I know it’s probably an auto-killzone thing that just kills you when you get to a point that is too low, so how would i disable it? The map I’m making anyways doesn’t even have any drop-off points.

Even though I knew it wasnt the case, I just wanted to see if it was a hieght-glitch, or even something related. So I built a hill then built a trench thingy on top of it, and I was able to walk in it just fine.
